Abstract:

Reasonably organization and reuse of the design knowledge enhance effectively the design efficiency for the concept design of the complex product. The design knowledge was described by terms of the basic element, the basic element extension set was studied, and a concept of basic element extension set of the knowledge reuse was introduced. A model calculating the degree of extension reuse was built based on the basic element. Optimization as well as searching and matching algorithms for the knowledge extension reuse were proposed. The feasibility and effectiveness of the suggested model were illustrated by an example of the concept design of a largescale hydraulic turbine.

Key words: artificial intelligence, complex mechanism concept design, knowledge reuse, basic element model, degree of extension reuse
